Why no $ before parameters?

[mrpinc]

Just read the interview you did on ActiveTuts (Great read BTW) and was just wondering if you could shed some light as to why Grant Skinner would recommend losing the “$” in front of parameter names. I find this style very useful for distinguishing passed parameters from class/method variables.

 

Thanks.

I felt exactly the same way, but Grant’s point was twofold (if I remember correctly):

 

1) Having “$” in front of all the parameters makes ASDocs less readable

 

2) It looks very “old school”, as the industry standard is to not use “$” in front of parameter names.

 

I became a big fan of using “$” in parameters and it was uncomfortable to let go of, but I’ve gotten used to it now. Removing them does make ASDocs more readable.

Perhaps then using $ for method parameters would work since they are not subject to asdocs. I use _ for all class variables and simply use getters and setters if they need to be visible in asdocs (I know I know, you lose some speed because of the method calls)

Why do you think method parameters are not subject to ASDocs? Last time I checked, they certainly were

Sorry, that was poorly chosen terminology. What I meant to say was, if method parameters are subject to ASdocs then perhaps method variables (that only exist within the scope of a function) could use the $ prefix. That way your params still are clean for ASdocs, and the other vars in the method (which are not subject to ASDocs from what i understand) would be differentiated from the passed params.
